| Abstract: | Disaster area ＆ occurrence area of mixed population of pine caterpillar were determined as main factor indexes. The main factor indexes were quantified comprehensively by using mathematical methods. Occurrence trend extent of occurrence for mixed population for pine caterpillar in Chaoyang City were evaluated by using abnormal analysis method. Result shows that：this method is scientific and accurate, and the evaluation results consistent with the actual situation. |
